Accidents happen, authorities made right choice to save the child

The mother at the Cincinnati Zoo kept her cool and acted wisely in the face of certain danger. Zookeepers also worked swiftly, facing the Hobson’s choice of killing a gorilla to save a toddler.

The Cincinnati Zoo killed this 450-pound gorilla named Harambe last week after a three-year-old boy accidentally fell into the gorilla's enclosure and was dragged through the water. Screen capture courtesy of NBC News
